PNEUMATIC STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 556,776, dated March 24, 1896.

Application filed June 8, 1895. $erial ITO-552.181. (No niodeld To all whom it may concern.-

Be it known that I, ALLEN A. RUssELL, a citizen of the United States, and a resident of Massillon, county of Stark, State of Ohio, have invented a new and useful Improvement in Pneumatic Straw-Stackers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

M y invention relates to an improvement in pneumatic straw-stackers.

The object of my invention is to simplify the construction and to provide a stacker which shall possess superior advantages with respect to durability and etticiency.

\Vith this obj ec-t in view the invention consists of certain features of construction and combination of parts,which will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a longitudinal sectional view of the rear portion of a thrashing-machine embodying my invention. Fig. 2 is a cross-section of the discharge-pipe on line a; of Fig. 1. Fig. 3 is a perspective view of my improved stacker. Fig. 4 is a longitudinal sectional view taken through the automatic shifting mechanism. Fig. 5 is a plan View of the same. Fig. 6 is a side elevation of the rear portion of the thrasher-frame, and Fig. 7 is a sectional view on line '3 y of Fig. 5.

In the drawings, A denotes a rear end portion of the thrasher-frame, to the lower portion of which is mounted the fan-casing B, which is arranged obliquely to the length of the thrashing-machine. The top of the easing is formed with an opening through which the straw to be stacked is fed. The casing has secured to its bottom a journal-box f, which projects upward into the casing and is in the form of a hollow truncated cone. A fan-shaft g is journaled in box f and has a central bore 7;, intersected near its lower end by transverse openings. Near the upper end of the shaft and secured thereto is a hub or spider h, to which the blades 2' of the fan C are attached. To the extreme upper end of the shaft is secured a grease-cup Z, over which is placed a conical cap m, by which the grease cup is protected from violence and the straw deflected from the center to the blades of the fan. In this connection it will be noticed that the conical box. f directs the dustand chaff from the center of the fan-box toward the ends thereof, where they will be m ore exposed to the action of the fan and be blown through the discharge-pipe. The fan is rotated by the power-shaft Z2, which is provided with a gear a in mesh with a gear j, secured to the lower end of the shaft g.

D denotes a platform which is secured to the rear end of the thrasher-frame at a point above the fan-casing. A metal plate E is supported on said platform and is provided with a central aperture surrounded by an annular groove or seat n, in which are placed anti friction-balls o. On the balls 0 is placed a turn table F, having in its upper and lower faces about a center aperture grooves 11 and q, and about its periphery a series of cogs or teeth '2. The turn-table is provided with a downwardly-projecting short sleeve .9, which projects into the central aperture in the plate E and also with an upwardly-projecting short sleeve 25. Antifriction-balls a are placed in the groove q, and placed over them is a binding-plate K, supported on sleeves or spools 1 through which bolts n: are passed into the plate E to hold the plate K in position.

To the sleeve is secured an elbow-section a, of the discharge-pipe L. Another section, b, has its lower end connected with the fanbox, while its upper end projects upward through the openings in the platform and plate E, and almost contacts with the lower end of the section 0.. The adjacent ends of these two sections of the discharge-pipe are surrounded by the sleeve .9 of the turn-table, which tightly engages the ends and forms an air-tight joint. 4

M denotes a band or ring which is bolted to the upper end of the sleeve 1, and from which project rearward arms 0'. A pipe-section 6'' has an elbow f, which passes down over the elbow-section a, and is connected to the arms a by arms (1', so as to have a swinging movement therewith. The arms d may be connected to the section 6 in anysuitablc 1nanner-as, for instance, by a ring or band N, as shown, which is cast integral with the arms.

Support-ing-standards O are secured to the ring M, one on each side of the dischargepipe, the upper ends of said standards being secured together by a pin y on which is journaled a sheave-wheel h. A brace-rod e is attached to the pin g with its upper end, and

its lower end is secured to lugs j projecting from the ring M. To the lugs j are secured vertical bars k, supported by a brace Z. A worm O is journaled at the upper end of the bars 7t and engages a worm-wheel m, secured to the end of the winding-drum n journaled between said bars 7a. This worm. is provided with a hand-wheel p. A cord q connects a clamping-ring secured to the outer end of pipe-section e, to the winding-drum n By turning the hand-wheel p to wind up the cord q the outer end of the discharge-pipe maybe raised. A reverse movement of the crank to unwind the cord will lower the discharge-pipe.

To lengthen or to shorten the dischargepipe I have provided novel means whereby section 0" thereof may be drawn telescopically on and over section a. To this end chain-wheels s, support-ed on lugs projected from rings N N, secured to the section e,,are provided with an endless chain 15. A rod a has one end secured to the lower run of the chain by a bolt r, while its other end is secured to the forward end of the section 0 By drawing the upper run of the chain forward the rod a will be moved back, and thereby carrying out section 1', thus lengthening the discharge-pipe. A reverse movement will draw the rod a and section 1" forward, thus shortening the pipe.

To rotate the table I have provided a shaft II, which is journaled in boxes a on the platform D. On one end of said shaft is fixed a worm G that engages the worm-teeth '7' on the periphery of the turn-table I and on the other end of the shaft is mounted a crankwheel P, by turning which the table F, with the upper sections a, c, and r of the discharge-pipe, will be rotated to oscillate or swing the discharge-pipe over the straw-stack or to turn it forward and over the machine for transportation.

To automatically oscillate the outer or rear end of the discharge-pipe or stacker, I have secured to shaft II gear-wheels Q Q, and on driving-shaft R, which is j ournaled in boxes a, are loosely mounted gear-wheels S S, one of which, S, engages wheel Q on shaft H, the other engaging an intermediate wheel T, j ournaled on a stud-shaft a, said wheel T engaging wheel Q. 011 shaft R between the wheels S S is a clutch U, secured to said shaft in a sliding relation by a spline or other device, and on the inner faces of the wheels S S are provided corresponding clutches a. Adjacent to the clutch is pivotally secured an operating-lever IV having right-angle prongs a that embrace the body of the clutch N between the clutch-heads a The lever IV eX- tends under the segmental rim X, on which are provided downwardly-projecting pins a that engage the end portion of the lever NV. 011 the under side of the lever \V is pivoted a coil-spring a", one end of which is secured to the lever, the other end to the plate a On theouter end of the shaft R is mounted a pulley Z. In operation the pulley Z, having a belt engagement with a similar pulley on the thrashing-machine, will continuously rotate the shaft in one direction. The clutch having engagement with one of the wheels S S will rotate the shaft 11 in one direction. The worm G, rotating the table F, will carry one of the pins a against the side of the end portion of the lever IV. The pin a will move the lever over to one side until the pin a passes the end of the lever, which will then be drawn back by the spring a and will throw one of the clutches U in engagement with one of the wheels S S, thereby reversing the movement of the shaft II, turn-a ble and discharge-pipe.

This movement will continue until the other pin a engages the opposite side of the lever *W' and reverses the movement of the parts.

In operation the straw and the chaff will fall naturally on the discharger or blower, (as the fan and its box may be properly termed,) placed, as it is, obliquely to the body of the thrasher. The straw then will be discharged through the discharge-pipe to the place of stacking.

For convenience in packing for transportation section a may be detached from its support, section b detached from the chamber 13, and the supportD removed from the thrasherframe, thereby decreasing the length of the machine.

Having thus described my invention, what I claim is 1. In a pneumatic straw-stacker, the combination of the centrally-aperturcd supportin gplate, having a circular groove or seat, a revoluble table provided with a coincident aperture, and with upwardly and downwardly proj ecting sleeves, said table having annular grooves or seats on its upper and lower faces. balls placed in the groove of the plate, balls placed in the upper groove of the turn-table. a binder-plate for securing the latter balls in position, a pneumatic discharge-pipe having the adjacent ends of two of its sections terminating within one of the sleeves of theturntable whereby an air-tight joint is formed. substantially as set forth.
